What year GT40 lower?

When I bought my cobra intake it was a legit 93 cobra upper but its a cheap chinese lower with the small oil baffle. Im worried that I'll get it all together and it will start using oil. So I'm gonna go to my local ford bone yard and scoop up an exploder intake. I will still be using EGR so what years would work for my setup? The car itself is a '92
 
Ive heard that sometimes changing the baffle doesnt fix the problem. Im kind of confused as to how the baffle causes the use of oil to begin with if someone could explain it to me. If the bigger baffle will fix the problem do I just call ford and ask for a 96 exploror lower intake baffle and specify "the big one"? And foxna6 the oiling problem isnt with the original cobras its with the newer ford racing lowers. I thought it had to do with a casting flaw but apparently its something to do with the oil baffle on the bottom.
 
Another option is to install an air-oil separator and just run what you got.

if the pcv sucks it in wouldnt it recirculate?

If the PCV sucks in oil, it goes into the intake and is then drawn into the cylinders where it is burned off along with the air/fuel. Then you have blue smoke coming out the tailpipes.

and where do i find the large baffle?

Junkyard or watch the classifieds, sometimes GT40 lowers pop up for cheap.

arent they riveted on from the factory? how does one attach it

They are press-in pins, IIRC. I've seen machine shops pull them out delicately enough that they are able to press them back in. If that doesn't work you could drill and tap the holes and run screws in there, but I would definitely be using Loc-Tite then.
